Understanding Induction Motor Performance – Why Settle for Speed Torque Curves
Monday, November 3 – 8:30 am until 10:00 am

This tutorial will present methods by which one may thoroughly and quite accurately assess the performance characteristics of single-phase or balanced multi-phase induction motors under running conditions without the use of a computer or a scientific calculator. The methods include a graphical and an analytical approach; the graphical method will be emphasized because of its simplicity and insightfulness. The mathematical complexity of either method is limited only to taking the square root of two squared numbers – and hence may be performed using the simplest of calculators [attendees will be provided with a 99-cent calculator for use in working out example problems]. Because of the hands-on approach of the tutorial, the enrollment must be limited to the first fifteen registrants.

Who should attend?
Anyone who needs to know… Given the model of a machine, how can one predict the principle output characteristics such as efficiency, speed, power factor maximum torque, etc.? Given the physical motor, how can one conduct some elementary tests, monitoring only machine outputs and shaft speed and predict total motor performance?
